IMPROVEMENT IN GULTIVATQR-TEETE.

TO ALL WHOM I'I MAY CONCERN:

B e it known that I, WILLIAM B. READY, of Sacramento, in the county ci' Sacramento, in the State of California, have invented a new and improved Method of Constructing Cultivator-Teeth; and I do hereby declare that the following. is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in constructing cultivator-teeth with an adjustable tongue, of steel or iron, or any other proper material, in such a manner that the actionof the point otthe said tongue may be continued until a large portion of its materia-l is consumed in its service, thereby inducing great economy in its use. p, i

` To enable others skilled in the art tc make and use my invention, I will proceed to describe its construction and operation. l i

Figu're 1 is a side elevation of the tooth,

Figure 2 a front elevation, and v Y l i Figure 3 a sketch-in perspective, giving a general view of the same.'

Figure 4', a section, showing groove, tc.

lThe stock a, or support ofthe adjustable tongue d, may be made of cast or wrought iron. It is provided 'with a groove, c, of proper width anddepth to admit the 'tongue'cL which groove extends from the shoulder b to the lower part of the stock. i The face of the stock a is formed with a curve, with which the tongue d concentrically corresponds, thus giving to the latter a solid bearing, whether it be raised or lowered. The stock a has also a hole, e, cast through it, for the admission of the bolt f, \vhich holds the tongue d to its place. In other respects, the stock a is construct-ed like ordinary cnltivator-teeth, and is provided Vwith flanges, g g, forattaching it to a frame, and with braces, h It, toY give it strength and-stiffness. p The tongue d is made of suitable material, steel, of course, being usually adopted, and formed ina shape concentric with the curve of the groove c and the portion of the shank of the stock a immediately above it, so 'Y that, throughout its whole' extent, it shall have a solid bearing. It is fitted to the groove c, whose sides are parallel, thus freely admitting of its being raised or lowered, while the sides ofthe groove hold it rmly against all lateral motion. Its lowerend -is properly pointed for u se, and its upper portion pierced with holes., z'zz'z',

or with slots, for the admission ofthe bolt f, bywhich it is firmly held, .the several holes or slots also being the means of adjustment to the point of the tongue when occasion requires, or when it becomes .worn away,

which adjustment is effected by changing the bolt to anydesired hole in the tongue.

What I 'claim as my invention, and desire 'to secure by Letters Patent, is- 1. The groove c in stock a, as a seat for an adjustable point for a cultivator-tooth. 2. The movable tongue d, pierced with holes or slots t'z'z', forming an adjustable Apoint of a cultivator-tooth. 3. The combination of the groovcd stock or support a with the adjustable tongue d, for-the purposes of a cultivator-tooth, substantially as above described.
